The PCI slot 0000:00: 1f.6 of the modem card may be disabled early in
a bootup process, but then enabled later. If modem drivers load
but the modem is not responsive, read Bootup.txt about possible fixes.
Send dmesg.txt along with ModemData.txt to discuss@xxxxxxxxxxxxx
if help is needed.

This is a NEW softmodem case! Please send the output ModemData.txt
to DISCUSS@xxxxxxxxxxxxx , even if further assistance is not needed.
It will enrich the Archive and help others!
-------------------------------------------
Lacking a dsp (digital signal processing) chip, the modem is a software
intensive or "softmodem" type. Its primary controller manages the traffic
with the CPU. But the software needed is specified in the Subsystem.
-----------------------------------------
Support type needed or chipset: slmodemd
An ALSA (Advanced Linux Sound Architecture) modem driver: snd-intel8x0m
provides Low Level support enabling contact with the modem hardware.
For all BUT Conexant chip soft modems (using hsfmodem software)
complementary High Level support is through a Smartlink utility:
slmodemd
Download from http://linmodems.technion.ac.il/packages/smartlink/
the package SLMODEMD.gcc4.0.tar.gz having a compiled slmodemd. Unpack
under Linux with:
$ tar zxf SLMODEMD.gcc4.0.tar.gz
and read instructions therein. But briefly, the modem is setup with
command:
sudo slmodemd -c YOUR_COUNTRY --alsa modem:1
reporting dynamic creation of ports:
/dev/ttySL0 --> /dev/pts/N , with N some number
Read Smartlink.txt and Modem/YourSystem.txt for follow through guidance.
Already loaded into the kernel is snd-intel8x0m and audio drivers it
depends on,
displayed by: lsmod | grep snd_intel8x0m
